“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— Warren Buffett
The wisdom of Warren Buffett reflects a value-based philosophy about investing that says investors are buying shares in a business, and encourages strategic thinking about investment time horizon. Before placing a buy order for a stock, a great question we can ask is whether we would still be comfortable making the investment if we couldn’t sell it for many years?
A “buy-and-hold” approach may call for a time horizon that spans a long period of time — maybe even lasting for a twenty year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of McKesson Corp (NYSE: MCK) back in 2006. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:
| Start date: | 02/10/2006 |
|
|||
| End date: | 02/09/2026 | ||||
| Start price/share: | $53.15 | ||||
| End price/share: | $962.32 | ||||
| Starting shares: | 188.15 | ||||
| Ending shares: | 218.97 | ||||
| Dividends reinvested/share: | $25.42 | ||||
| Total return: | 2,007.17% | ||||
| Average annual return: | 16.45% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $210,627.31 | ||||
As we can see, the twenty year investment result worked out exceptionally well, with an annualized rate of return of 16.45%. This would have turned a $10K investment made 20 years ago into $210,627.31 today (as of 02/09/2026). On a total return basis, that’s a result of 2,007.17% (something to think about: how might MCK shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
Notice that McKesson Corp paid investors a total of $25.42/share in dividends over the 20 holding period, marking a second component of the total return beyond share price change alone. Much like watering a tree, reinvesting dividends can help an investment to grow over time — for the above calculations we assume dividend reinvestment (and for this exercise the closing price on ex-date is used for the reinvestment of a given dividend).
Based upon the most recent annualized dividend rate of 3.28/share, we calculate that MCK has a current yield of approximately 0.34%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.28 against the original $53.15/share purchase price. This works out to a yield on cost of 0.64%.
